Ask HN: How do you recover from a bad day?

When you have had a bad day, what do you normally do to take your mind off/switch-context just to feel better/not-shitty...

Does anyone have any routines like some games, books or some other activity (apart from exercise as it's normally already 8ish in night when you realize the day is gone, and it was quite horrible, and you don't have much energy or motivation left to go to gym or a run...)
